Structural characteristics and working principle
1, the output of the implementing agencies through the valve stem on the role of the main spool, is designed to a certain angle, the main spool, converted into horizontal force around, but also through the secondary spool, sealing plate squeeze the two seats to form a double Negative seal, the seal does not leak, the torque is small, the switch valve seal with friction-free, fundamentally solve the spool stuck in the valve body or open the shortcomings of the phenomenon.
2, the pneumatic actuator adopts piston-type mechanism, the solenoid valve as the upper and lower part of the cylinder to control intake and exhaust switching elements to control the vertical opening and closing pieces for vertical displacement to control the valve opening and closing purposes,
3, with the use of the echo device for sending the valve switch-like signal, solenoid valve to achieve long-distance control, centralized control, automatic control, and on-site operation.
5, the valve opening and closing state of the scene instructions, the coat of the extension of the indicator rod to rise and fall, marking the valve is fully open (outrigger in the highest position), the valve is fully closed (outrigger in the lowest position).
6, with a single spring-reset pneumatic device or air tank to ensure that the power supply, air supply failure automatically switch, safe, reliable, speed, environmental protection, energy saving.
